l Application led November 27, 1905. Serial No. 289,369.

- vard Malesherbes, Paris, France, have in- -vented certain new anduseful Im rove` mentsrRelating to the Propulsion or Sub-` marine Boats,of which the 4following is' a specification. This invention relates toan apparatus for the propulsionof submarine or submergible vessels, andits object is to permit of adopting an internal combustion engine foroperating such vessels both on the surface and when submerged', withoutnecessitating two separate motors for these purposes, while avolding theinconveniences and complications result-ing from the employmentofelectric aceumulators. A According to this invention, the explosiongas lengine is fed in a closed cycle, fi. e.,with

out air beimT utilized for the combustion of the fuel. 'Fhe combustiongases exhaust i into a purifier or washer, Where the steam iscond-ensedand lthe `carbonio-acid partly absorbed, "so that an inert gasis obtained, which is then added with oxygen and is capable of beingagain utilized in the engine for producing iquid fuel.

In the accompanying drawings Figures 1 and 1EL are views in elevationsof the various devices constituting the apparatus and taken togetherconstitute a complete elevation of an explosive mixture with the of theapparatus, and taken together constitute a complete plan ofthe device.

a' is the explosive gas or combustion motory of exhausting outside thevesselwhen on the surfaceor exhausting into the puriiier or dissolverwhen operating in a closed `cycle When submerged.

At b2 is shown the union connecting the three-way cock to the puriiieror dissolver.

f is the purifier which instead of being a ro- ,tary apparatus ofthe-Standard type, as in the example given in a French Patent No.309,633 is a plate type washer, in order to the device, and Figs. 2--2JLare views in plan' avoid having a large liquid capacityrwhichfisimportant owing to the'dis 'lacementvdffthe center of gravity due to t ejpitcliingfaiid tossing ,of the-vessel. `With the same object andwiththe same success, the inventor vhas utilized pulverized Water oralkaliirei-iiqiiid Washers of the Koerting type.

g indicates an excess gas outletwhichf-.is only utilized-in cases vinwhich thel puriiicationis not complete.' In suclrca-sesfthe'exlcess ofas unabsorbed. in the purifier would accumulate in the cycle, andnaliythe ressure would become such that it Woul exceed the pressure ofthe. oxygen supply at p, so that this latter would be un'abl'eto intro*-lduce the oxygen into the-cycle which Would result in the stopping ofthe motor. As soon as the pressure in .the cycle, Whiciris about 10 c.m. of water, increases abnormally, the bell regulator brises andopensthe=cockg, which regulates the supply to the suction chamber of the gaspump '7c shown in Fig. v1, which forces this excess into the sea,usually in the" Wake formed by the screw in such 'a manner as to comletely dissolve the' gases. The pump-,7c is sufgciently the excess asout at a dept of- 50 meters.-

i is a bre l regulator similar to theforego'- ing and romwhicli themotor sucks the ordinary air at a constant pressure, through the' pipei2 Which terminatesat the two three- Way cocks y'. During propulsion onthe-surface, that is to say inan open cycle, -these cocks lare turned insuch a Way that the suc-- sup lied and the motor operating in a closedvCy c e. v Z are the oxygen stora e tubes which may, of course, bereplaced y an appropriate means for the production o this as on1powerful to force board Z1 is the oxygen collector Z2 the ranch forintroducingv oxygen to fill these tubes.

m is the oxygen reducing valve which reduces the pressure from120'kilograms or 1 more to 1- kilogram, which is the pressure in thereservoir vtube n. It -is this reservoir (tube a that feeds the motor bthe intermediaryof the bell regulator o vwiiich acts upon the cock o1. pisthe oxygen distributing valve With the regulating cocks g.

r are the fuel pumps (which may be gasoiio Iene, splrlt or the like)each of which supplies a air of cylinders.

n the accompanyinr drawing the Washing of the gases may e effected withsea Water Which is taken in at t and supplied 'to the )urifier at i!1see Fig. 2, this Water being discharged into the tank u and finally intothe sea by the pump y. In this case the .urification is only partial. Inorder to efect complete purification and to obtain a perfectly closedcycle, the tank u is filled with an alkaline liquid (such as causticsoda, caustic otash or the like) and the ump y causes t iis liquid tocirculate throng i a pipe (which is not shown) in the Washer untilexhausted, it then being forced into the sea and replaced by freshliquid. Under these con- 'ditions the tank should be of sufficient sizefor a submersion of several hours.

3 indicate the inlet and outlet 4for the circulating cooling Water ofthe motor.

By applying this apparatus the Weight aild Volume ofthe propulsion meansof a subl marine vessel are considerably reduced, and

. forth the com it 1s also possible to maintain constancy in the Weightof the boat and preserve the interior atmosphere from vitiation.

Having now particularly described and ascertained the nature of saidinvention and in what manner the same is to be performed, I declare'that what I claim is:

1. In an ap aratus for the purpose set forth, the comliination of anexplosion gas engine, a gas pipe, a silencer placed thereon,

anexhaust Valve, a purifier, a three-way cock permitting either ofexhausting outside the vessel or into the purifier, a pipe leading fronrthe purifier for supplying the purified exhaust gases to the clmine, apump for the excess gases and an oxygen supply to the engme. 2. In an aparatus for the purpose set liination of an explosion gas engineexhausting into a purifier, an excess gas outwith a cock controlled bymeans of a bell regulator, a gas pump for forcing the excess gas intothe sea, a pipe leading fromthe purifier for supplying the purifiedexhaust gases to the engine, and an oxygen supply to the engine.

3. In an ap )aratus for the purpose set forth, the combination of anexplosion gas engine exhausting into a purifier, an excess gas pump, abell regulator for theaspiration of the gases and a pipe for supplyingthe exhaust gases, three-Way cocks arranged on said pipe for supplyingeither atmospheric air or exhaust gases to the motor, oxygen storagetubes lconnected with a reducing valve and With a reservoir tube, a pipefor supplying oxygen to the motor and an oxygen distributing valve withregulating cocks.

4. In an ap aratus for the purpose set forth, the com ination of anexplosion gas engine exhausting into a purifler, a seawater supply tosaid purifier, a discharge tank connected with the purifier, a pump forcausing the water to circulate througl the purifier and for expellingthe washing water into the sea, an excess gas pump, a bell regulator forthe aspiration of the gases and a pipe leading to the motor, three-waycocks arranged on said pipe for supplying either atmospheric air orexhaust gases to the motor, oxygen storage tubes connected with areducing valve and with a reservoir tube, a pipe for supplying oxygen tothe l motor and an oxygen distributing valve with regulating cocks.

5. In an ap )aratus for. the purpose set forth, the com )inatiou of anexplosion gas engine, an exhaust valve. connected with a purifier orwashru, a plate type washer having a small liquid surface, a sea-watersupply to the Washer, a discharge tank connectedwith said washer, a pumpfor causing the water to circulate through the. purifier and forexpelling the washing water into the sea, an outlet and an inlet for thecirculating coolingr water of .the motor, an excess gas pump, a bellregulator for the aspiration of the gases and a pipe for the supply ofexhaust gases, three-Way cocks arranged on said pipe for supplyingeither atmospheric air or exhaust gases` to the motor, oxygen storagetubes connected with a reducing Valve and with a reservoir tube,a. pipefor supplying oxygen to the motor` an oxygen distributing Valve withregulating cocks and fuel pumps for supplying the motor.

In testimony whereof l have hereunto placed my hand at Paris, Francethis eleventh day of November, 1905.
